Older Upper Scorpius disks show reduced molecular emission and hints of higher inner-gas C/O ratios than young disks, indicating chemical evolution consistent with pebble drift.

A new grid of disk models with grain-surface CO chemistry plus an ML inference tool produces gas mass estimates from ALMA observations that match independent dynamical and HD values without requiring extreme elemental depletion.
ALMA survey detects H2CO in 45% of 20 disks and finds strong correlations of line luminosity with disk size, mass, and stellar luminosity, suggesting grain-surface formation.
Multi-wavelength data on V1094 Sco support a hybrid origin for its ring-gap structures consisting of planet-disk interaction at ~100 au and secular gravitational instability at 170-230 au in a low-turbulence disk.
ALMA observed 3933 independent coordinates in nearby star-forming regions for disks and planet formation, analyzed by sky location, frequency coverage, exposure time, spectral lines, and angular resolution.
